This automated loading equipment, featuring dual conveyor belts and a truss handling mechanism, significantly improves efficiency through a dual-side synchronous operation mode. The system’s modular design supports multi-scenario adaptation and is particularly suitable for the automated loading of regular goods such as bagged and boxed items, showing broad application prospects in industries such as grain and oil, chemicals, and building materials.
Structural Design
The system adopts a parallel layout of dual conveyor belts, forming a central truck entry channel and equipped with at least one truss handling mechanism. The truss main body adopts a gantry structure, including two vertical support bodies and a horizontal support body higher than the truck. Movement and positioning along the conveyor belt direction are achieved through guide rails and a sprocket travel mechanism (positioning accuracy is ensured by sprocket drive, supporting frequent starts and stops without slippage). This structure allows loading operations to be performed simultaneously from both sides after the truck stops, nearly doubling the efficiency compared to traditional single-side operations.
Key Functional Modules
- Material Picking and Temporary Storage Module: Located at the truss picking station, it includes a tiltable and adjustable feeding conveyor roller and a multi-layer temporary storage platform. The track path switching between the conveyor rollers and the conveyor belt/picking platform is achieved through a flip-drive mechanism, and the cargo buffering and anti-blocking control are implemented in conjunction with a sensing module. The picking platform is designed with clearance openings and roller gaps that match the gripper fingers to ensure interference-free gripping.
- Cargo Handling Module: Equipped with multiple sets of three-dimensional driven grippers, each gripper includes two grippers with gripping fingers. A gear set synchronous drive mechanism achieves symmetrical movement of the grippers on both sides, ensuring cargo levelness. The gripper mounting frame integrates a rotary drive function, supporting 0-90° angle adjustment to meet the needs of different palletizing modes. The three-dimensional drive module achieves precise positioning in the X/Y/Z directions, allowing the gripper to directly reach into the carriage for stacking, and controlling the drop height to a minimum to ensure neat stacking.

Competitive Advantages
Leading Efficiency: Dual-sided synchronous operation + temporary buffer design improves efficiency by more than 60% compared to articulated robotic arms, and by 25-30% compared to traditional gantry-type robotic arms.
Palletizing Quality: Utilizing low-drop-height and synchronous clamping technology, the pallet arrangement is significantly neater than that of high-throw-down articulated robotic arms, solving the problem of “chaotic pallet arrangement” common with traditional robotic arms.
High Adaptability: Supports 1-2 gantry mechanism configurations, with customizable gripper numbers, capable of handling goods of different sizes and adaptable to various truck models.
Market Application Prospects
Particularly suitable for the continuous loading needs of medium to large-sized manufacturing enterprises, with successful cases already existing in industries such as cement and fertilizer. Its modular design allows for flexible configuration according to site conditions, and the sprocket drive mechanism ensures long-term stable operation in dusty environments. It can effectively solve the shortage of new-generation loading and unloading workers, while significantly reducing safety risks and lowering the cargo damage rate to below 0.5%.
